Houston-based Quantlab Financial LLC, a high-frequency trading firm with offices in Boston, San Francisco and London, plans to move its area headquarters into 3 Greenway Plaza this fall.

The firm uses extremely fast computers to predict prices and patterns in the trading market, which can then be used to execute a high volume of trades in a short period of time.

It currently employs around 140 people in its Houston office, according to Tim McInturf, executive vice president and general counsel for Quantlab.

The new office at Greenway Plaza will be two floors and around 50,000 square feet. It will allow Quantlab to continue to hire in the market. The company currently occupies around 35,000 square feet at 4200 Montrose Boulevard, McInturf said.

3 Greenway Plaza recently underwent a $5 million renovation following Irving, Texas-based Exxon Mobil Corp.'s exodus from the building to its new campus in Springwoods Village.

Quantlab is using Trademark Construction Inc. for the demolition of the new space and PDR as its interior architect. It has not signed a contractor for the construction of the new office.

In May 2015, the company settled a lawsuit with SXP Analytics LLC that claimed SXP Analytics allegedly stole Quantlab's high-frequency trading algorithm, Bloomberg reported at the time.
